Wound closure with plug
First Claim
1. A method for closing a wound in a wall of a vessel, comprising the steps of:
- a) mating a positioning tool with a plug comprising an elastic material;
b) inserting the plug into a passageway of a sleeve such that a distal retainer of the plug is compressed in the passageway of the sleeve, the sleeve having a distal end extending through the vessel wall in the vessel;
c) pushing the plug through the passageway of the sleeve with the positioning tool such that the distal retainer exits the distal end of the sleeve and expands in the vessel; and
d) positioning the plug in the wound of the vessel wall, wherein the positioning step (d) comprises the step of pulling the expanded distal retainer against the distal end of the sleeve with the positioning tool to disengage the positioning tool from the plug.

Abstract
An elastic, biodegradable plug has a proximal retainer and a distal retainer coupled by a waist. The plug may be positioned to straddle a wound in a blood vessel wall of a patient and therefore close the wound to stop bleeding through the wound. To position the plug in the wound, an operator may insert the plug into a sleeve extending through the vessel wall into the vessel and move the plug through the sleeve with a positioning tool. In the sleeve, the distal and proximal retainers of the plug are compressed. As the distal retainer of the plug exits the distal end of the sleeve into the vessel, the distal retainer expands in the vessel such that a surface of the distal retainer faces an inner side of the vessel wall. The positioning tool and the sleeve are then removed to position the waist in the wound of the vessel wall and allow the proximal retainer to expand such that a surface of the proximal retainer faces an outer side of the vessel wall.
